A buttery crust and a slightly tangy lime filling make up these beautiful Lime Bars. The perfect summer dessert! A CITRUS DESSERT BAR Just like your favorite Lemon Bars, these Lime Bars have the perfect balance of tanginess, sweet, and a hint of tartness. They’re refreshing to enjoy, especially after a hot summer day! They don’t require all that much hard work to whip up and you can enjoy other summer activities like enjoying some pool time while you wait on these to chill in the fridge. These lime bars are a bit more mellow than your traditional key lime bars which is what I love about them! FREQUENTLY ASKED QUESTIONS:  What’s the difference between regular limes and Key Limes? Key limes are smaller and more fragrant than regular limes. They have a higher acidity and are more tart. Regular limes, on the other hand, are larger, less acidic and have a slightly less tart flavor. What kind of limes do I need to use for Lime Bars? I used regular limes but key limes can be substituted in this recipe. What other crust options can I try? Instead of this buttery crust, try a graham cracker crumb crust for the bottom layer. How do I make sure the bars cut cleanly? Wiping the blade of your knife in between cuts is helpful to keep your bars nice and clean with smooth edges. Additionally, you can run the blade of the knife under warm water and drying it off before using it to help get smooth cut lines. How to store leftover Lime Bars? Leftover bars should be stored in an airtight container and can be kept for up to a week. You can also freeze these bars for up to 3 months.

HOW TO MAKE LIME BARS Preheat the oven to 350F degrees. Line a 9×13-inch baking pan with parchment paper or spray with nonstick baking spray. Set aside. In a bowl (or the bowl of a stand mixer), sift together 2 1/2 cups flour, powdered sugar, and salt.  Then add the melted butter and mix until combined. Put the crust dough into the lined pan and press into a flat thin layer with the bottom of a measuring cup. Bake for about 20 minutes, until a light golden color around the edges. In a food processor or stand mixer, add in the sugar and the lime zest. Mix until the zest is fully incorporated. Add remaining half cup of flour to the sugar mixture and pulse again.  Add lime juice, eggs, and green food coloring (optional), and mix until completely combined. Pour the filling over the crust and place in oven. Bake for about 30-40 minutes, turning the  pan after 15 minutes. Check for doneness by wiggling the pan. If it doesn’t jiggle in the  middle, it’s done. Do not overbake.  Remove from the oven and allow to cool for about an hour before chilling in the refrigerator. Then chill for at least two hours. When ready, dust heavily with powdered sugar and then cut into 16 bars. Optional: Sprinkle the tops with additional lime zest.  CRAVING MORE RECIPES?  Classic Lemon Bars Homemade Key Lime Pie Lime Jell-O Poke Cake Key Lime Poke Cake Blueberry Lemon Bars 3-Ingredient Lemon Bars Creamy Lemon Bars Peaches and Cream Bars Strawberries and Cream Bars Pecan Pie Bars Print Lime Bars A buttery crust and a slightly tangy lime filling make up these beautiful Lime Bars.
